Gainclone speaker cables and OTA diy

[neutron7]

IMOH dont let aluminium anywhere near your system. especially in the wiring.

aluminium oxidizes on contacts as current passes. it is a cheap and crappy metal anyways ever see a sax made of aluminium? its also sounds bad.

there is a reason aluminium house wiring was banned in most countries after peoples houses burned down.

however kings/dukes/lords etc of old thought aluminium was godlike material, spent tons of money to get aluminium spoons and forks made . then the ones who were not killed by their ofspring or spies/poison/wives/ all got alsheimers and died.

its rough and ready and easy to machine and work with but why not use normal shielding instead of BAD METAL!

Note 47 Labs do not recommend twisting the OTA cables as it'll increase the capacitance. This is a very imporant point as some GC, especially ones without the zobels to go into oscilliation. Friend of mine made some cat5 twisted cables and his GC went into oscilliation, sounded like the speaker cone was cracking up.

I don't know about 47Labs, but I can tell you my experience. We test IGC and NIGC amps with about 6m braided cables made with Cat5, using no zobels, and there was no oscillation whatsoever.

This cable was made "TNT style", braiding 4 cat-5 cables, so the internal wires were not braided. Braiding each wire like on other cables, with lots of pairs, will probably increase capacitance much more.

Perhaps your friend used such cable or no output resistor.
